How many watts of power do I need to ride at velocity?

If you apply watts of power, you will ride at velocity 20.81 mph . If you want to ride at velocity mph, you must apply 231.43 watts of power. This web page uses physical models of forces on a cyclist to help you estimate the relationship between power P (watts) and velocity V (kph or mph) of a cyclist.

How do you calculate the wattage of a bike?

The cycling wattage formula that we use looks like this: P = (Fg + Fr + Fa) * v / (1 - loss) where: P is your power, Fg is the resisting force due to gravity, Fr is the rolling resistance force,

How many watts of power does a cyclist produce?

Utilize cycling power estimates to gain an idea of how much power in watts you are generating. At 12.5 mph, you’ll generate about 75 watts on average.

How many watts do I need to increase my speed?

Approach your calculation a different way if you are trying to determine how many additional watts you need to gain speed increases. If you are expending 75 watts and traveling 20 kmh, or 12.5 mph, you need another 20 watts to raise your speed by 2.5 kmh to 22.5 kmh, or 14 mph. However, this is not a linear equation.

How many watts do I need on a speed bike?

At 12.5 mph, you'll generate about 75 watts on average. Use these averages: 95 watts for 14 mph, 120 watts for 15.6 mph, 148 watts for 17.2 mph, 180 watts for 18.7 mph, 218 watts for 20.3 mph, 262 watts for 21.9 mph, 311 watts for 23.4 mph and 366 watts for 25 mph.

How many watts is 22 mph?

what's interesting in link 4 is that you can play with different equipment and see theoretical time savings. It says that based on someone 180 pound, 20mph is 162 watts and 22mph is 209 watts, so, an increase of 47 watts.

How do you calculate watts cycling?

To calculate the wattage you need three components: Gravity Fg , with formula Fg = g * sin(arctan(slope)) * (M + m) , where: g is the gravitational parameter; and. M and m the masses of cyclist and bike, respectively.

Is 160 watts good cycling?

No exact watt number is appropriate for all riders. Generally speaking, a beginner cyclist may average around 75–100 watts in a 1-hour workout. A fit participant will average more than 100 watts, and pro cyclists can reach 400 watts per hour.

How fast is a 300 watt bike?

A 300 watt electric bike will typically reach speeds of 32-35km/hour unassisted.

How fast is 750 watts in mph?

Is 300 watts a good FTP?

The article claims that a typical fit cyclist might be able to crank out 250 to 300 watts as an average for a 20 minute FTP (functional threshold point) test, while the pros usually average 400 watts.

What is a good W kg cycling?

Generally, untrained riders have an FTP below 2.0 W/kg for men and 1.5 W/kg for women, while professional racers may be capable of sustaining more than 6.0 W/kg for men and 5.5 for women.

How do I calculate my cycling speed?

To calculate average speed, divide the total distance traveled by the total time. For example, suppose a cyclist travels 32 kilometers during the first 2 hours. Then, the cyclist travels 13 kilometers during the next hour. The average speed of the cyclist is the total distance divided by the total time.

How do I calculate my FTP for cycling?

Cycling. Functional Threshold Power (FTP): You can estimate FTP with your best recent 20-minute power value (either from a dedicated 20-minute test or a sufficiently hard 20-minute effort from a race or workout). Multiply that value by 95% to get your FTP.

How are watts calculated on an exercise bike?

There is a difference between Joules (Watts*time) produced and Joules (Calories) burned. The difference is the bodies efficiency and is approx 25% or a factor of 1/4. Then there is the constant factor between Joules and Calories which is 4.18. So by mere coincidence Power [Watts] * Time [Seconds] ~= Calories burned.

Is it worth calculating what wattage you need to maintain a certain cycling speed?

However, before you sign up and start number crunching, as a coach, I’d question the value of such a target from a motivational perspective and whether you’re trying to do things the wrong way round.

About this calculator

Because the speed of a cyclist depends on many factors, the above calculator will only give you a rough idea of the power to speed ratio in terms of the aerodynamic drag coefficient CdA. In order to do so the calculator has to make a few assumptions.

The drag area CdA

The CdA is the product of the real drag coefficient c d (often also named c w) and A - the frontal area of rider and bike. The CdA of a road cyclist, riding with his hands on the hoods can be around 0.4 m 2, while the best time trialists and triathletes achieve CdAs as low as 0.2 m 2 .

Here you can find an extend version of the Power to Speed Calculator together with some notes on the calculator and the formulas behind it.

What factors affect power output?

These include how much your bike weighs, your weight, your positioning on your bike and the air temperature. Other factors that come into play include your wheel diameter, crank length and gear ratio.

To convert your kilometers per hour to miles per hour, divide the kmh by 1.6. Advertisement .

Is a power meter good for cycling?

A power meter can provide an extremely accurate measure for gauging the intensity of your workout, but it's also an extremely expensive gadget. Unless you are training hard and seriously for a cycling race, triathlon or other event, this tool is really more of a luxury than a necessary workout aid. Still, it's nice to know how cycling power works.
